With apologies if this has been asked before; I did a cursory search but couldn't find anything (and I'm on my phone which probably doesn't help).
I was on a TfL Rail service at Romford today at 1804 and I randomly spotted a set of Virgin Trains' carriages being carted along by a couple of AGA power cars, passing through on the up main. I was just curious if this is a temporary thing or a regular occurrence of stock swapping from one main line to the other? I'm not a regular in this neck of the woods but it certainly caught my eye. Thanks!
